AS324/324A

LOW POWER QUAD OPERATIONAL AMPLIFIERS

Description

The AS324/324A consist of four independent, high gain and internally

frequency compensated operational amplifiers. They are specifically

designed to operate from a single power supply. Operation from split

power supplies is also possible and the low power supply current

drain is independent of the magnitude of the power supply voltage.

Typical applications include transducer amplifiers, DC gain blocks and

most conventional operational amplifier circuits.

The AS324/324A series are compatible with industry standard 324.

The AS324A has more stringent input offset voltage than AS324.

The AS324 is available in SO-14 and TSSOP-14 packages, and the

AS324A is available in SO-14 package.
